Update: I ran the chipper for over an hour and a half, keeping the seat forward, with no shut offs. I even tried bouncing the seat in normal position to see if it would trigger the shutoff, but it didn't. The only thing is that I shut off the engine a couple times when the chipper gummed up with...

I'm confident in the one part of my seat switch, because it shuts off if I start to leave the seat while in gear. But if there's a separate connection to the PTO that is does the same thing unless the seat is up, then it makes sense that it would be similar to your description. That's one of my...

@Russell King and @North Idaho Wolfman Thanks for those comments. I'll try to see if it keeps running with the seat forward. That would definitely be the best/easiest solution. Maybe the seat-forward detector is faulty until it runs for awhile, then it makes the connection and shuts the engine off

When you don't tilt the seat forward, does the PTO not even engage? Or does it run for awhile (sometimes 45 minutes) before stopping? And does not tilting the seat cause the engine to quit, or just prevent the PTO from engaging?

I haven't had to press anything, just move the PTO lever to the operating position while standing outside the cab. Since it runs for awhile, it doesn't seem to need any weight on the seat.

On my L4630 GST, I have been using a friend's chipper/shredder on the PTO, and it works fine for about a half hour, then the tractor shuts off with no indications it's about to quit--no bogging down, no shuddering, it just stops. I can restart it immediately but it shuts down quicker after that...
